Let’s be generous, it will uplift the investors pretty well once they start charging the real token costs and maybe drive out a few competitors.

> The Vikings didn’t “conquer” new lands the way you might imagine. Rather than just raiding, they often settled, intermingled with the locals farmers and established new states

There aren’t any the viking settlements in the Americas from that time? Or at least evidence of intermingling with the locals.

2.5) Your car doesn’t start

I will start now but I think not for long. “For your own safety we disabled your car”.

> Germany. It is good for people who are content with a middling but comfortable life. That's why most ambitious people leave.

Just curious how well does that work? I assume it’s being able to have a job, have a place to live, travel once a year. Medical care not tied to employment but hopefully easily accessible?

> So let's say your house has a thatched roof in California

You mean like a temporary shelter in woods or maybe it’s a translation issue?

> Assuming you haven't lived in the US I think you're severely underestimating some of the stupidity going on

Speaking of, having a thatched roof in a dry fire prone area would sort of fall in the same category.

The ~spice~ inference must flow.

Some of the data centers now run disconnected on gas turbines 24/7, which is better for electricity prices but they can be big nuisance for people living nearby.

But that's not a country. And in their case it's also true that policy set up by the structure can go against the interests of individual countries.

Oh me? I am fine, never had anything to do with. I just worked in the lab nearby. But glad you're glad I am ok!

They did feel threatened yeah. Not scary as in unwashed or scary looking, more like "unhinged" scary, as in "they could slash my tires" or physically attack and such.

Like I wrote before is that it signals to the outsiders that things in CA are actually pretty well. The biggest problems are solved if the top of the agenda is to police 3D printers. That’s at least how it should be. I am being sarcastic, of course, I’ve seem the homeless in San Francisco and I am sure that’s not the only major problem.

That boy knows what he is doing. Kids figure this stuff out they are no dummies. You don’t like so and so? Tell teachers they printed a “gun”. Or mentioned “gun” or said a politically incorrect word. It’s a form of bullying using a system’s irrationality against others. Kind of like swatting

> They could just ignore Trump as he has no authority to so limit a private company.

Ignore export control regulations?

I think you’re trying to say you really feel it’s not fair, and you’d like so and so meany and bully to go and pound sand. And yeah most people feel the same way here but ignoring export control regulations is not a joking matter and not something to play around with. Especially for a company that feels they are having extra eyes on them.

This is just not how it works even if we really, really want it to work that way. US government can do it, and has done it before. At some point strong encryption was considered “munitions” and export controlled. If SSL can be “munition”, LLMs can be slapped on a label just like that. SSL/TLS stopped being qualified as such eventually so some sanity was restored. But as the legal and regulatory framework, it’s certainly there and has and is being used in that capacity.

For a moment I entertained the idea that these are intentionally bad to get people to buy them as gag gifts. My kids and I certainly had a good laugh looking at the pictures in blog. That second picture of the jaw sticking out had my son ROFL-ing.

> boffins willing to go on the record as describing Microsoft's work as "unreliable" and perhaps even "fraudulent."

> Microsoft insisted its work is sound and in early June 2026 announced Majorana 2, a "next-generation topological quantum chip" it developed with the help of its own agentic AI.

AI hallucinates quantum computing bullshit as well or better than humans can hallucinate quantum computing bullshit. Couldn't have a better combination of technologies helping each other out.

> this literally is about ibm providing free cloud infrastructure and offering support for the community.

My comment is literally about the same thing. Does IBM provide x86 and ARM workers or s390x only?

> what failures are you talking about? s390x is not an "exotic" architecture by any stretch and is pretty top-notch in terms of availability, reliance and performance

I am talking about timeouts in CI blocking the whole pipeline, odd failures with JVM not working, hitting some jit corner cases, I am talking about kernel level concurrency bugs, and so on. I've seen them all. How much should a volunteer oss library maintainer spend debugging that?

> s390x is not an "exotic" architecture by any stretch and is pretty top-notch in terms of availability, reliance and performance, which is why it is still in use.

It is so me. I don't see a reason to care for it.

> the incentives both for the community supporting it and the manufacturer supporting the community seem pretty evident to me.

Not evident to me. Unless there is some other kind of incentive involved, they agree to fix other bugs, provide CI workers for other architectures, pay for support and so on.

What does an open source project get from this? Supporting s390x can be a pain. Their CI instances are over provisioned and time-out, sometimes odd failures due to the odd architecture, maybe performance issues. That's more headaches and toil from volunteers. So besides the bragging rights (I guess?) and discovering latent bugs exposed by the exotic architecture, what's in it for a project to deal with this extra architecture
